SPECIFICATIQN forming part of Letters Patent No. 307,626, dated November 1-, 1884.
Application filed .IIune f2, 1884. (N0 model.)
To aZZ whom it may concern:
Be it known that I, ROLAND L. Znnwnn, of Hartford, in the county of Hartford and State of Connecticut, have invented a new Improve- 5 ment in Magazine Fire-Arms; and I do hereby declare the following, when taken in conncction with accompanying drawings and the let ters of reference marked thereon, to be a full, clear, and exact description of the same, and
which said drawings constitute part'of this specification, and represent, in-
Figure 1,
a sectional side view showing all the parts in the closed position; Fig. 2, a vertical section on line a"- :v of Fig. 1; Fig. 3, asectional side view showing the parts as in the first part of the opening movement; Fig. 4, I
same view showing the position of the parts as they approach the opening movement; Fig. 5, the same showing the parts inthe extreme open position; Fig. 6, a top view, the breechpiece removed, showing the top of the car rier and the graspingiinger levers thereon in their open position; Fig. 7, the same levers and fingers in the closed or grasping position. Fig. 8, a transverse section through the fingers in their open position; Fig. 9, the same with the fingers in the closed or grasping position. Fig. 10, a modification ofthe lever which raises the carrier.
This invention relates to an improvement in that class of breech-loading fire-arms in which the breech-piece is arranged to move longitudinally in a line with the barrelrearward in opening and forward in closing the breech the said breech-piece actuated by a lever ex tending down through the receiver, and so as to form the trigger-guard below, and in which a magazine isarranged beneath and parallel with the barrel, but parts of my invention being applicable to single breech-loading firearms, the principal object of my invention being to make a dead-lock for the breech-piece in its closed position; and it consists in the construction as hereinafter described, and more particularly recited in the claims.
A represents the receiver, which is of substantially the usual outline, terminating at the rear in a tang, 13, above and a tang, C, below, and by which the receiver is secured to the stock.
receive the barrel 0, and the magazineD also, in the usual manner, the general outline of the arm being substantially that of the class of arms to which my invention particularly relates.
E is the breeclrpiece, arranged to movelongitudinally in the receiver in axial line with the barrel, and is guided and supported in such movement by its peculiar shape and corresponding shape of the opening through the receiver, and also by a longitudinal groove, a, on each side the breech-piece, near its for- .ward end, and corresponding studs in the receiver, as seen in Fig. 2.
F is thehammer, which is hung upon a pivot, I), in thereceiver, and so as to turn thereon in the usual manner, and is caught in its several positions by the trigger G, and from which it is released by a pull of the trigger, in the usual manner, and when so rel eased the mainspring H throws the hammer forward to deliver its blow.
I is the triggerguard lever, of usual shape, hung in the receiver upon a pivot, (1, forward of the trigger. Above the pivot (Z the lever extends to form two arms, J and K.
L is the locking-dog hung upon the under side of the breeclrpieeo on a pivot, 0, its forward end concentric with the pivot, and the seat in the breech-piece of corresponding shape, so that the surface of the dog around the pivot end fits closely the corresponding surface in the breech-piece. This dog is arranged to swing up and down, as from the position in Fig. l to that in Fig. 2. In each side of the receiver is an abutment, M, below the breech-piece,against the forward end of which the rear end of the dog stands in its closed position, as seen in Fig. 1. Upon the under side of the dog a notch,f, is formed corresponding to the end of the arm .I of the actuating-lever, and in which that arm plays like the tooth of a gear, standing in the closed position seen in Fig. 1. If the actuating'lever I be turned down, as seen in Fig. 3, the arm J will strike the rear side of the notch fin the dog L, and will raise the dog from the position seen in Fig. 1 to that seen in Fig. 3, and this first movement of the lever therefore raises the dog from its locked position against the abutments M to a position above and clear of those abutments. The abutments are arranged one upon each side, as before stated, a space between them being necessary for the passage of the downwardly-projecting part of the dog, as well as of the arms of the lever in.
the rear movement. The arm K extends up into a recess, N, in the breech-piece, but so that when the parts stand in their closed position the rear face of the arm K is forward of the rear end, g, of the recess N, and is so far forward of that rear surface, 9, as to permit the lever to be turned from the position in 1 to that in Fig. 3, so as to unlock the breech-piece before the arm K comes to a bearing on the surface g, and as seen in Fig. 3. The breech-piece being unlocked, as described, the arm K now comes in contact with the surface 9, and from that point the downward movement of the lover I being continued, say as to the position seen in Fig. 5, the arm K causes a corresponding rear movement of the breech-piece to its fully-open position. At this time the forward face, h, of the recess N stands substantially against the forward face of the arm K, and so that inreturning the lever to the position seen in Fig. 3 the forward face of the arm K bears against the forward face of the recess N and returns the breech-piece to its closed position. At this ti me the actuati ng-lever I has not quite reached its closed position. In completing the movement of the lever I, it is moved from the position seen in Fig. 3 to that seen in Fig. 1. In so doing the dog L is turned, down from its position as seen in Fig. 3 to that seen in Fig. 1, and in front of the abutment M. which looks the breech-piece inits closed position. The arm K escapes from its bearing upon the forward face, h, of the recess N, and thereby avoids the strain upon the pivot of the actu; ating-lever, as must be the case where that lever serves as the support for the breech-piece against recoil.
O is the firing-pin arranged longitudinally through the breech-piece in the usual manner, and terminating at its forward end in the center point, a. When the parts are in their closed position, the firing-pin is free for longitudinal movement under the influence of the hammer, or otherwise.
Upon the back of the dog L is a cam, P, which works up and down through a correspouding recess, Q, in the firing-pin, the cam acting against the rear end, i, of thisxrecess. In the first movement of the lever I, which raises the dog L from its position in Fig. 1 to that in Fig. 3, the cam P strikes the rear face, t, of the recess Q in the firing-pin, and forces the firing-pin rearward from the positionseen inbrokeu lines. Fig. 3, to the. position indicated in full linesin same figure; and this first movement of the tiringpin draws its point inwardand away from the front face of the breech-piece, and so that it cannot be. moved to present its point forward'of' the front face of the breech-piece until the dog is turned downward from the position seen in Fig. 3 to that seen in Fig. 1, in which position the firing-pin is left free for longitudinal move ment.
To turn thehammer rearward and in advance of the rear movement of the firing-pin or breech-piece, and so that in such movement it shall be entirely free from possible contact with the firing-pin. I introduce a strut, B, one end of which is hung to the upper arm of the actuating-lever above the pivot, as at Z. The strut extends rearward and is connected to the hub of the hammer forward of its pivot by a link, S, the link hinged both to the strut and to the hub of the hammer. The rear end of the strut bears against ashoulder, m, onthe hammer, as seen in Fig. 1. In the first part of the downward movement of the actuatinglever-.as from the position in Fig. 1 to that in Fig. 3-,the strut, bearing against the shoulder m, turns the hammer to half-cock, as seen in Fig. 3, the link S holding the strut in contact with the shoulder at in this movement. In completing the downward or opening movement of the lever, the strut R continues the openingmovement of the hammer until it arrives at full-cock position, as seen in Fig. 4.
Atthat time the pivotlof the strut in the lever passes below the, central line drawn'from the pivot (Z of the lever to the rear end of the strut, and in so passing below the rear end of the strut moves forward, the link' S permitting it so to do, and so as to take the strut from the shoulder m on the hammer, leaving the hammer at full-cock, and as seen in Fig. 4:. The rear movement of the hammer is therefore considerably in advance of the rear movement of the breech-piece, the hammer standing at full-cock while the rear movement of the breech-piece is continued,
and so that the breech-piece will pass over and clear from the hammer, and whereby the rear movement of the hammer is only made to the extent necessary for it to properly deliver its blow, the breech-piece passing on over the hammer after the movement of the hammer is stopped. One great advantage of this arrangement of the strut, hammer, and lever with relation to the breech-piece is that by throwing the end of the strut which is hinged to the lever below a line drawn from the pivot of the lever and the pivot between the link and the hammer, so that the rear movement of the breech-piece may be continued after the ham mer has arrived at-its full-cocked position, I am enabled to employ a long cartridge without any additional rear movement of the hammer, which must be necessary where the hammer, lever, and breech-piece are connected, so that the rear movement of the hammer and breecl1- piece continue together tothe extreme rear position, and under which arrangement the rear movement of the hammer would be much greater than would be necessary for the delivery of the blow. The under side of the breech-piece is recessed, as seen in Fig. 2, and from its down position, Fig; 4, to that seen in as seen in broken lines, Fig. 4, in order that it may escape the nose of the hammer as it passes over it.
To prevent the accidental fall or release of the hammer until all the parts shall be securely locked in position preparatorytoreceive the blow ofthe hammer, I arrangealcverin the receiver upon a pivot, 12, one arm, T, of which extends forward to a position beneath the rear end of the dog. The other arm, U, extends rearward and stands over a projection or shoulder, p, on the trigger in rearof thepivot. VVhin the dog is down. as seen in Fig. 1, it bears against the forward arm, T, of the lever, and so as to hold the rear arm, U, up and away from the projection p on the trigger, leaving the trigger free to be pulled; but as soon as the dog rises the lever is turned, under the action of a spring, V, to throw the forward end upward, following the dog into the position seen in Fig. 3. This movement throws the rear arm, U, downward andupon the projection 12 on the trigger, so as t5 prevent the trigger being pulled from its hold on the sear of the hammer, and the hammer is substantially locked in its corked position until the dog returns to its locked position, as seen in Fig. 1, in which movementitstrikes the forward arm, T, of the lever and turns the arm U from its position of engagement with the projection p on the trigger.
As thus far described the mechanism of the arm is applicable to single breech-loaders as well as to magazinearms.
I will now describe the mechanism which, acting in connection with that heretofore described, adapts the construction to a magazine gun.
WV is the carrier, hung at its rear end upon a pivot, 1". In rear of the pivot a spring, y, bears against the rear end of the carrier, substantially in line with the pivot, the action of the spring being upward when the carrier is in its down position, as seen in Fig. 1, but so that as the carrier is raised to the position seen in Fig. 5 the bearing upon the spring comes below the pivot, and the spring tends to hold the carrier in its up position.
In the receiver underneath the carrier a lever, 2, is hung upon a pivot, 3, to extend I rearward from the pivot, and so as to bear up on the under side of the carrier forward ofits pivot. This lever and its operation are best seen in Figs. 4 and 5.
On the hub of the leverI is a cam or shoulder, 4, and on the under side of the lever 2 a corresponding shoulder, 5. As the breechpiece approaches its extreme rear position and the lever I its forward position the shoulder 4 on the lover I strikes the shoulder 5 on the lever 2, and then as the forward movement of the lever I is completed the lever 2 is turned from the position seen in Fig. 4 to that seen in Fig. 5, and as the lever 2 bears against the under side of the carrier it raises the carrier Fig. 5, the spring y engaging the carrier so as to hold it, as before described, in. either of the said two positions. by a downward projection, 6, from the breeclr piece, which works through a longitudinal slot in the carrier, and so that as'thc breechpiece approaches its closing position itstrikes an incline, 7. on the carrier, and riding upon that incline turns the carrier downward from the position seen in Fig. 5 to that seen in Fig. 4. In the bottom of the receiver ala-tch, 8, is hung at its rear end upon a pivot, 9. Beneath it is a Spring, 10, the action of which is to force..8o
the latch upward, so that its nose may stand at the rear end of the magazine, and against the head ofthe cartridgetherein,as seen in Fig. 4, and serve as a stop for the column of cartridges in the magazine. the pivot, is a bearing, 11, upon which the arm K of the actuatinglever will strike in its extreme forward position, and so as to turn the nose of the latch down away from its position as a stop to the magazine, and as seen in Fig.
1. In this down position the real-most cartridge of the magazine passes over the latch and against the downward project-ion 6 on the breech-piece, and so that vas the breechpiecc commences its rear movement the rearmost cartridge in the magazine will follow it upon the carrier, as seen in Fig. 4. The latch 8 being free, so soon as the actuating-lever starts it will rise into its position,(scen in Fi 4,) and so as to come in rear of the head of the next cartridge. and serve as a stop for the column of cartridges. and there remain until the parts are returned into their com pletelv-closed position, when the arm K strikes the bearing 11 on the latch and turnsit downward, as seen in Fig. 1. The receiver is constructed with a side openng for the charging of the magazine, as indicated. in broken lines, Fig. 1, when the parts are in their closed position; but this side open- I IO ing or method of charging the magazine is no part of my present invention, and therefore needs no description, further than to say that it may be any of the known constructions of opening for such purpose. passes from the magazine onto the carrier, as seen in Fig. 4, it would lie there free were there not some device to hold it. Such freedom ot' the cartridge upon the carrier is objectionable, owing to the liability of the car- I20 tridge dropping from the recess in the receiver when the arm is inverted, or the liability of the cartridge to be thrown out by the ascent of the carrier under a quick action of the lever I. To hold the cartridge upon the carrier and 1 2 5 avoid these difficulties, I arrange a pair of levers on the upper surface of the carrier, and so as to swing in a horizontal plane. These levers are hung upon the top of the carrierone at each side-upon apivot, 12.
18, of each lever extends forward and terminates in a finger, 14, which fingers are of a The carrier is returned 70 On this latclnabove 85 As the cartridge One arm, 13.)
shape upon their inside to grasp the body of the cartridge. The other arm, 15, of the le vers extends rearward, one each side of the upper arm of the actuating-lever. On each side of the upper part of the lever I, and between the two arms L K, a cam, 16, is formed,
which, as the aetuatinglever is turned rearward, as from the.position in Fig. 3 to that in Fig. 4, passes down between the tails of the levers, and so as to force those tails, say, as from the position seen in Fig. 6 to that seen in Fig. 7, and such outward movement of the tails of the levers causes their forward or finger ends to approach each other, as seen in Fig. 7. position, as seen in Fig. 6, the space between them permits the free rear movement of the cartridge onto the carrier and between. the fur 'gers, as seen in Fig. 8; but as the actuatinglever is turned rearward the fingers approach each other and grasp the cartridge, as seen in Figs. 7 and 9, held in that grasped position by the cams 16, standing between thetails of the levers, and those cams so remain until, in the forward movement of the actuatinglevcr,they pass above the tails; but at that time the breech-piece is moved so far forward as to have carried the cartridge into its chamber in the barrel, and so far that its position is assured. The continued movement of the cartridge between the fingers causes them to turn outward for the passage of the head between them.
The fingers swing freely in a horizontal plane, and are closed by the action of the cams, but free to open by the forward movement of the cartridge. The breech-piece is provided with the usual hooked extractor, 17, and correspending shoulder, 18, on the face ofthe breechpiece below-too wel known to require particular description.
The connection betweeirthe actuating-lever and the hammerthat is, the strut R and the link S connecting the lever and the hammer may be employed in many known constructions of arms in which the connection between the said lever and the breech-piece differs from the mechanism herein described. I therefore do not wish to be understood as limiting this part of my invention to a particular connection between said lever and breech-piece.
IVhile I prefer to hang the lever 2, through which the carrier is raised, on a pivot forward of the shoulder 5, this lever may be in the shape of a bell-crank lever, as seen in Fig. 10. In that case the shoulder 5 becomes the shorter arm of the lever, and will be acted upon by the cam 4 on the lever, the same as in the first-- described construction.
I am aware that a strut has been arranged between the lever and the hammer, connected to the hammer by a link, whereby the hammer is thrown backward; but in such'constru ct-ion the same actuating-lever has been in positive connection withithe breech-piece, and so that the first movement of the hammer and the first movement of the breech-piece are As these fingers stand in their openv simultaneous, and the movement of the hammer continues throughout the entire movement of the breech-piece. I therefore do not claim, broadly, astrut-like connection between the actuating-lever and the hammer.
I claim v1. In a fire-arm, the combination of a longitudinally-movable breech-piece, E, the dog L, hinged at its forward end to the breechpiece, and so that its rear end may swing up and down, an abutment, M, in the receiver at the rear, against which the rear end of the dog may be turned when the breech-piece is in its closed positionfand the actuating-lever, one arm of which forms the trigger-guard, the said lever extended up into the receiver, one arm, J, in connection with the dog L, the other breech-piece, and whereby, in the first move ment of the actuating-lever, the arm J will turn the dog up from its locked position, and then, in the continued movement of the actuating-lever, the other arm, K, will throw the breech-piece rearward, and on the return of the lever the arm K in the first part of the movement will throw the breech-piece into its 'closed position, and then the arm J turn the bolt into its locked position, substantially a described.
